Abstract

<p>Seals and hoses for oilfield applications are often exposed to high temperatures, aggressive fluids and various gases. A specific failure, termed rapid gas decompression failure, can occur during the decompression process of material exposed to high pressure and various gaseous environments. This paper deals with the failure process of the material during these extreme conditions. Especially the crack initiation and the crack growth process were investigated with tear growth experiments and correlated to decompression experiments with an autoclave. Moreover, the experimental material (hydrogenated nitrile butadiene rubber) was tested at different temperatures to catch the temperature influence. Apart from the described experiments also standard material characterizations as well as specific tests to cover polymer and filler interaction were performed [1].</p>
